Patent CA-2343028-A1 (CA)
Inventor: GOULD RUSSELL J
IPC: B29C48/08
Filed: 1999-08-02
Abstract: A method of making a high strength polyester strap, preferably a coextruded polyethylene terephthalate, suitable for higher load applications that typically require steel strapping. The coextruded strap has a core of highly  oriented PET and a skin or outer surface of a PET which has been impact modified. The strap is made by a process in which a coextruded strand (or sheet) is subjected to a plurality of stretching steps with a final stretch ratio of at least 5 to 1. In a preferred embodiment, the strap has an outermost layer in which the brittleness of the strap is reduced and the toughness is increased by the inclusion of an elastomer, which has been foun d to significantly improve the weldability of the strap.

Abstract: An intramedullary nail apparatus includes an elongated nail body having a longer section and a shorter section. A detachable connection affixes the larger and shorter sections together end to end, using a taper lock connection, for example. The shorter section can provide transverse openings therethrough for enabling one or more fasteners to attach it to bone tissue, depending upon the medical indication. The nail includes a bow that consists of two tangent radii. This bow allows for the anterior bow of the femur and the relative strightness of the tibia. Thus, the apparatus of the present invention enables the same stems to be used in the treatment of femoral and tibial fractures. A stem is selected for any indication based on the desired diameter and length. The bow allows for a simplified surgical technique and a reduction in inventory of the nail system.

Title: System and method of automatically conveying a wireless office system (wos) frequency set to mobile stations
Inventor: RAHMAN AKBAR
IPC: H04W88/06
Filed: 1999-09-17
Abstract: A system and method in a radio telecommunications network for automatically conveying a Wireless Office System (WOS) frequency set to a mobile station (MS) (29) belonging to the WOS. The network includes a public cell (23), and a private WOS (24) located within the public cell. A WOS controller (25) sends the WOS frequency set from the WOS to an Equipment Identity Register (EIR) (28) in the network whenever the WOS changes its frequency set. When the MS  registers in the public cell in which the WOS is located, a mobile switching center (MSC) (21) serving the public cell notifies an Intelligent Roaming Database (IRDB) (26) of the registration. The IRDB fetches the WOS frequency set from the database, and obtains location information for the MS from a home location register (HLR) (27). The IRDB then sends the WOS frequency set to the MS in an IS-136 R-DATA message.

Abstract: A field marker attachable to as outer end of an agricultural implement comprises an arm pivotally attachable to the implement extending perpendicular to the travel direction. A marking device is attached at a distal end of the arm. An extendable hydraulic cylinder is attached to the arm and implement and moves in one direction to a stopped position where the arm is in the operating position. An active hydraulic source supplies hydraulic fluid at an operating pressure such that the cylinder remains at the stopped position until a rearward force on the arm causes the pressure in the cylinder to exceed the operating pressure and the arm moves rearward. Where the marking device scores the field, a wheel can be mounted on the arm such that its axis of rotation is removed from the center of the wheel so that the scoring device moves up and down scoring an intermittent line.

Abstract: A support ring for holding a fabric seat on an inclined frame tube of a portable chair frame allows the support ring to rest horizontally on the inclined frame tube so as to enable the fabric seat also resting horizontally on the chair frame. The support ring has a supporting hole contributed by two semi-circular portions and an intermediate portion extended between the two semi-circular portions. Each of the semi-circular portions has a diameter equal to or slightly larger than a diameter of the inclined frame tube. The intermediate portion also has a width equal to the diameter of the semi-circular portion. When the inclined frame tube fittingly passes through the supporting hole and is supported inclinedly with the horizontal, the support ring can be horizontally mounted on the inclined frame tube while a lower half of the frame tube resting on an upper edge of one of the semi-circular portion of the supporting hole and an upper half of the frame tube supporting by a lower edge of the another semi-circular portion of the supporting hole. Therefore, the fabric seat can be mounted horizontally on the chair frame and the downwardly force applied on the fabric seat can be evenly distributed and supported around the support ring.
